1 1​

Answer 1

Answer:

Step-by-step explanation:

Check whether the value given in the brackets is a solution to the given equation or not: (a) n + 5 = 19 (n = 1) (b) 7n + 5 = 19 (n = -2) (c) 7n + 5 = 10 (n = 2). (d) 4p – 3 = 13 (p ... LHS = 7 * (-2) + 5 = -14 + 5 = -9 ≠ RHS. So, n = -2 is not the ... 7m + 7 = 77 ... x = 25/4. (e) 8y = 36. => 8y/8 = 36/8 [Dividing both sides by 8]. => y = 9/2.
